IMPROVEMENTS IN THE MANUFACTURE OF CLAY PIPES.

TO ALL WHOM IT MAY .CONCERN1' Be it known that I, Gaonen D. GOODRICH, of the, town of Joliet, in the .countyiof Will, and State of Illinois, have invented new and usefnlImpi-ovements in the Manufacture of Clay Pipes; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 represents the side elevation of my devices,

Figure 2 represents the back view of the device tofasten to, and to disengage from, the frame of the trough carriage; and I Figure 3 represents the vertical section of the water-box and the mouthpiece. The nature of my invention consists, first, in substituting for a hook or catch operated directly by the hand,

with which the carriage on'which the trough in a machine for making clay pipes continuously is placed and moved, a device, consisting of a spring, treadle, and standard, which, by the pressure of theifoot, performs the required operation; second, in constructing. and arranging amovable mouth-piece, instead of stationary one, placed at the orifice of the die, to better hold up, guide, and preserve the following pipe during the opera:

tion of cutting off the pipe, and while the pipe cut off is being removed with its trough. and a new trough substitnted in place of the one removed; third, in placing a box or reservoir with water at or over the orifice of the die, so constructed that the pipe is continuously 'wet as it passes out of the die and on the trough.

To' enable others skilled in the art to make and use my invention, I will describe its construction and operation.

All my improvements are-applied to clay-pipe-making machines of that class which forcethe pipes out continuously. The device to control the trough-carriage consists in the following: Spring A, supported by the blocks a a, fastened to the platform of the machine, has a standard, 13 in its centre, which, passing through the notch Z) of the cross-piece'O of the'frame of the machine, reaches with its end the bottom of the trough=carriage D, ata point directly behind the block E, fastened to the bottom of the carriage.- The standard passes also through a loop of the treadle F, hinged at one end of the platform of the machine, with its centre resting on thespring, and its other end projecting out of the frame of the machine.

The operationconsists in this, that when the carriage 1), with its trough, G, upon it, is in its place, the end of the standard B, abutting to the block E, keeps the carriage fast, while the pipe, coming out of the die N, passes out and along the trough G; but when the forward end of the pipe reaches the end, 9, of the trough, the foot is pressed on the treadle F, the carriage is disengaged, and slides back by: and with the motion of the pipe, thus permittingthe workmen to out it off at the end 9 of the trough, which, with the pipe, is then takcn'ofi and another trough put in its place.

My mouth-piece H, at the orifice of the die N, consists of an independent block, I, of metal or other mate rial, and the two arms K K entering grooves made in the frame supporting it. v

The operation of this arrangement consists in this, that when the end of the pipe, after coming out of the orifice of the die on to the trough, reaches the end, 9, of the same, and the disengager, being acted upon, permits the carriage D, with the trough G by and with the motion of the moving pipe, to slide backward, the trough is followed by the mouth-piece H, carried in the same way by the movement and pressure of the pipe, until after the pipe is cut oif and taken away with the trough, and an empty trough is placed in the proper position, with its end,

g, under the end of the out coming pipe, in which operation the mouth-piece H is forced hack to its proper posi= tion under the orifice of the die N, andthe operation is repeated. The movable mouth-piece guides, supports,

and preserves the end of the pipe, after the operation of the cut-ofi' is performed, far better than a stationary one, thereby saving that portion of the pipe, which, with the present mode of operation, is generally injured and thrown away.

My reservoir It consists of a metallic box, (which may he made of any other form or material'for the pur-' pose in'tended,) whose sides taper downwards to the bottom 1', which is perforated with one or more holes, and above this bottom there is a false bottom, P, in which an opening, p, (one or more,) is made, and into which a sponge, S, is placed. This reservoir or watery-box is fastened above the orifice of the die N, and may be supplied with water from another Teservoir placed above or near it. When supplied with water filtered through thespongc, it discharges the same through its perforated bottom, 7', on the pipe, while it proceeds from the machine.

Having thus described my devices, I state that I do not claim the invention of the catch, or that of the mouth-piece; but i hat I do claim, and desire to secure by Letters Patent, is-- 1. The improved method of fastening the trough-carriage in, and disengaging the same from, its rigid and described position on the frame on which it rests, substantially as herein described and specified, or other equivalent devices. I l

2. The movable mouth-piece H, arranged substantially as herein described and specified..

3. The combination, in a machine for the manufacture of clay pipes, of the trough for receiving the pipe, and the apparatus for lubricating the pipe as it issues from the month of the machine, substantially as described;

4. Each of three devices to be used in combination with the clay-pipe-making machines, running the pipe continuously, and using the metallic or metallic lined troughs.
